PATTERN IVIECHANISM FOR LOOIVIS.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed July 23, 1904. Serial No. 217,831.

To all whom, tn/tay concern:

Be it known that I, EPPA H. RYoN, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented certain new and useful Improvements inPattern Mechanism for Looms, of which the following is aspecication.

My invention relates to improvements in looms, and more particularly toimprovements in the pattern mechanism of looms and to that class ofpattern mechanisms in which a long heavy pattern-chain is required for along pattern or a pattern with two or morediiferent weaves.

The object of my invention is to improve upon the pattern mechanismsreferred to and more particularly to do away with the long 'heavypattern-'chain ordinarily required for long patterns or patterns withdifferent weaves and to substitute a pattern-chain composed of theconstruction and operation thereof.

Referring to the drawings, Figure 1 is a front View of a detachedportion of a loomhead with my improvements applied thereto looking inthe direction of arrow a, Fig. 3. Fig. 2 corresponds to Fig. 1; but someof the parts shown in Fig. 1 are removed and others broken away to showthe other parts more clearly. Fig. 3 isan end view of the parts shown inFig. 1 looking in the direction of arrow same figure; and Fig. 4corresponds to Fig. 3; but some of the parts shown in Fig. 3 are removedand other parts are shown to more clearly illustrate my improvements.

In the accompanying drawings, 1 is the arch-bracket. 2 is a stand boltedthereto and on which the several parts of the mechanism are supported.The harness-pattern-chain shaft 3 is mounted -in bearings on the stand 2and has fast thereon a gear 4.

5 is the lower-cylinder gear-shaft having fast thereon a pinion 6, whichmeshes with the pattern-chain gear 4.

7 is the upper-cylinder gear-shaft.

The upper and lower cylinder gears, vibrator-levers, vibrator-gears, andthe vibratorconnector to the harness-jacks are of the ordinary andWell-known construction and operation in what is ordinarily' termed theKnowles head-motion and are shown by broken lines and full lines inFigs. 1 and 2.

Fast on the upper-cylinder gear-shaft 7 is a cam 8, adjustably securedthereon, in this instance by two set-screws 8. (See Fig. 2.) The cam 8is engaged by and operates a camlever 9, pivoted on a shaft 10. Thecam-lever 9 carries one end of a griff 11. The other end of the gri' 11is carried by a lever (not shown) on the back side of the'head-motioncorresponding to the lever 9. The griff 11 is adapted to engage andraise the hook-wires 12, connected with the vibrator-levers 12. Thecam-lever 9 has also on its inner side a projecting plate or knife 13,adapted to engage the upper end of a hook-wire 14, which is connected atits lower end to a lever 15. (See Fig. 4.) The lever 15 has a hub 15',secured on a rock-shaft 16 by a set-screw 17. (See Fig. 2.)

Fast on the outer end of the rock-shaft 16 is the hub 18 of a shipperlever or arm 18,

Also fast on the star-wheel shaft 20 is in this i instance a barrel orcylinder 24, having pins 24 of different length extending out therefrom(see Figs. 2 and 4) and forming a pattern-surface. The pins 24 areadapted to engage the under surface of a lever 25,`pivoted at one end ona stud 26 and connected at its other end,

Vthrough a connector 27, with a slotted opening 28 in the lever 28. Thelever 28 is'piv'- oted at one end on a stud 29 (see Fig. 1) and carriesat its other end one end of a rock-shaft 29. on whichis fast the lowerend of an arm 30, in this instance made in two parts adjustablyconnected. l Ther upper end of the arm 30 has mounted therein theextended journal lor IOO end 31' on the card-cylinder head 31 of thecard-cylinder, which cylinder supports the pattern-cards 32 in theordinary way. The pattern-cards 32 are in this instance punched withfour rows of holes 32 for a four-weave motion; but said cards may haveless than four rows of holes, if desired. On the cardcylinder journal 31is also pivoted one end of a rod 33. (See Fig. 1.) The other end of therod 33 is attached to an eccentric-strap 34 on the eccentric 35, whichis fast on the end of the cylinder-shaft 7. (See Fig. 1.) The rotationof the shaft 7, through eccentric 35, strap 34, and rod 33, communicatesa swinging motion to the upright arm 30 and a corresponding upright armat the back side of the head-motion (not shown) and also a swinging orreciprocating out-and-in motionv to the card-cylinder and the cards 32thereon in the ordinary way. A pawl 36, pivoted on a stud 37, in thisinstance catches over the projecting pins 31 on the cylinder-head 31 asthe cylinder is moved outwardly and acts to turn or rotate the cylinderin the ordinary way and cause the cards 32 to rotate therewith, saidcards having holes 32 at their ends, which engage pins 31 at the ends ofthe card-cylinder in the usual way. y

The upright arm 30 is preferably made in two parts, as shown, to give anadjustment by means of a bolt 30 on the upper part eX- tending through aslot 30 in the lower part. (See Fig. 3.) Extending outwardly from theupper part of the lever 30 is an extension or arm 30a, havinga bearing301, which supports one end of a rod 38, secured thereon by a setscrew38. The rod 38 extends horizontally in front of the card-chain 32 (seeFig. 3) and is supported at its other end. (Not shown.) The lower end ofa flat spring 40 is secured to the rod 38 by a set-screw 40' (see Fig.3) and bears against the pattern-cards 32 to keep them in place on thecard-cylinder as it revolves. On the end of the rod 38 is secured by ascrew 41 the upper end of an arm 41. The lower end of the arm 41 carriesone end of a rod 42, on which is mounted a roll 43.l (see Fig. 1,)around which passes a cord 43. Said cord also passes around thecard-cylinder under the cards 32 and acts to strip the cards off thecylinder as it revolves.

rlhe indications of the pattern-cards 32 are communicated through thehorizontally-moving indicator-needles 46, which extend th rough and aresupported in holes through bars 39, which extend transversely throughthe headmotion. The indicator-needles 46 have eyes 46 therein, throughwhich extend the hooks 12. The outer indicator-needle 46ais shorter andhas an eye 46" therein, through which extends the hook 14. Theindicator-needles 46 are actuated by spiral springs in the ordinary way,and a spiral spring 47 -actuates the needle 46,

A spiral spring 48 is attached at one end to the arm 15, to which thelower end of the wire hook 14 is attached, and said spring is attachedat its other end to a stationary part of the frame. The spring 48 actsto rock the shaft 16 and, through arm 18 and collar 19, move the shaft2O longitudinally and hold the star-wheel 21 out of line with the pins23 on the pin-Wheel 23, as shown in Fig. 4.

From the above description, ln connection with the drawings, theoperation of my improvements will be readily understood b v thoseskilled in the art and briefly is as follows: The upper and lowercylinder gearshafts 7 and 5 make a revolution at each pick of the loom,while the harness-pattern chainshaft gear 4 and pin-wheel 23 thereonmake but one-sixth of a revolution at each revolution of the cylindergear-shafts. The eccentric 35 on the upper-cylinder gear-shaft beingconnected, through strap 34 and rod 33, with the pattern-card cylindermoves said card-cylinder toward and away from the indicatorneedles 46,which move hook-wires 12 according to the indications of thepattern-cards 32 or allow them to hook over the griff 11 and be liftedinto a raised position as the cam 8 acts upon the cam-lever 9 and raisesit to its highest position. rlhe raising of the hook-wires 12 raises thevibrator-levers 12, to which they are attached, and also thevibrator-gears, to be acted on by the u pper-cylinder gear in the usualway, and the lowering of the hook-wires 12 lowers the vibrator-levers 12and also the vibrator-gears, to be acted on by the lowercylinder gear.When it is time for the weave of the pattern to be changed, thepattern-card 32, having holes through it for such indication, comes intoproper position to allow the indicator-needle 46, which is connectedwith the hook-wire 14. to be acted upon by the spiral spring 47 andcause said hook-wire 14 to hook over and engage the lift-plate 13 and beraised by the upward movement of the cam-lever 9 when raised by therevolution of the cam 8. The upward movement of the hook-wire 14,through arm 15, rocks the shaft 16, and throughv arm 18, engaging thecollar 19, moves the shaft 20, carrying the star-wheel 21, so that thestar-wheel 21 will be in alinement with and adapted to be engaged by thepins 23 on the pin-wheel 23. A pin 23 on the pin-wheel 23, engaging aslot 21 in the starwheel 21, communicates a rotary motion to thestar-wheel 21 the shaft 20, and the cylinder 24, carrying the pins 24',causing the pin 24 in engagement with the lever 25 to move out ofengagement with said lever and another pin, either shorter or longer, tocome under and engage said lever 25 and cause said lever to be movedinto a higher position or to drop into a lower position and throughconnector 27 raise or lower the lever 28, and the upright lever 30,carrying the pattern-card cylinder, to raise or lower the pattern-cardcylinder and bring another set of openings in the pat- IOO IIO

tern-cards 32 in line with the indicator-needles 46 and the needle 46,

It will be understood that the pattern-cards 32 may have four rows ofholes 32 therein, as shown, or less than four rows of holes and that thecorresponding rows of holes on each card make up one pattern or acertain weave, and through the automatic raising or lowering of thecard-cylinder, as above described, by means of the pins 24 on thecylinder 24 or equivalent pattern mechanism engaging the lever 25, theproper position will be auto.- matically given to any one of the rows ofholes in the pattern-cards 32 for the indications of said holes on theindicator-needles 46 and the needle 46". It will thus be seen that aVery long pattern may be made from light-weight pattern-cards and thatas each row of holes on the pattern-cards may be of a diierent patternor weave a number of different patterns or weaves may be obtained andthe automatic change from one weave to another is easily accomplished.

It will be understood that the details of construction of myimprovements may be varied,

if desired. A flexible pattern-chain may be substituted for the cylinder24 with the pattern-pins 24@ if preferred.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
